Applicare la formula: $\int_{a}^{b} cxdx$$=c\int_{a}^{b} xdx$, dove $a=0$, $b=t$, $c=s^2$ e $x=b$

Applicare la formula: $x\cdot x^n$$=x^{\left(n+1\right)}$, dove $x^nx=s^2\int_{0}^{t} bdbs$, $x=s$, $x^n=s^2$ e $n=2$

Applicare la formula: $\int xdx$$=\frac{1}{2}x^2+C$, dove $x=b$

Applicare la formula: $\left[x\right]_{a}^{b}$$=eval\left(x,b\right)-eval\left(x,a\right)+C$, dove $a=0$, $b=t$ e $x=\frac{1}{2}b^2$
